I'm looking hard at the 3988 to accomodate our ever expanding family. I'm looking for your suggestions on what to look for as I evaluate individual boats. I'm leaning toward the 330's.

Any things to consistently look out for in this model?

(I know to look for holes in the hull....)

Thanks in advance!

Three girls under 10, one wife.

We like to cruise with my brother in law and his family, also. Seems to work good with the adults in two staterooms and kids in sleeping bags all over the place. Our 3058 was pretty cramped this summer.

Great boat for family cruising. With 4 adults and some kids you will have plently of room for short cruises and the 2 heads will make it very comfortable.

I second this - but with your size family and the sleeping bags it shouldn't be a problem. This is a great boat and I can't think of anything other than the usual things you would check in any boat. If you have a choice it obviously comes down to condition and any extras that have been added e.g. diesel heat, thrusters, davit systems, enclosures etc. Good luck.

The 270 and the 330 are the same engine with different turbo charged air cooling and, consequently, different hp RATINGS. Since the 3988 should require about 200 hp to move the boat along smartly, the two engines should be capable of moving the boat the same. The 270 hp version would, of course, be working at a higher percentage of its RATED load but since they would be operating at the same ACTUAL load, there should be little perceptable difference.

The difference in cooling, mentioned above, is the cooling water temperature running throught the aftercooler. The 330 RATED engine uses sea water while the 270 RATED engine uses engine coolant which is, perhaps, 100°F hotter than typical seawater. Otherwise the two different engines will see the same loads and the same wear and the same life.

Both engines should give you about 20 knots at 20 USgph or somewhere around one mile per gallon. Ignore the engine ratings and go according to the sea trials.

My 95 3988 has the 250 Hino's and I am perfectly content with the performance. I actually wanted this year to get the cost down and I wanted the fuel efficiency of the smaller motors. Two to four knots slower than the 330's but that is ok. I cruise at 19 knots at 2700 rpm (WOT 3000) if I am in a hurry. Love the boat.

I used to sell yachts for the Bayliner dealership in southern cal, after I retired so I could be around boats all year. many times we took the 39 out for sea trials man what a nice boat very, very, stable the 330s were so sweet with power to spare, never got to drive one with the 270s. hope this helped.

Just sea trialed our 3988 last week. 18.5 knots at 2300 according to gps. Probably would have ran out a lot better, but when we hauled her for the survey the bottom was pretty over grown ( local diver had supposedly just cleaned her ). We ran our sea trail on SF Bay in a 30-40 knot blow, boat handled just great but it was a bit misty on the fly bridge. Practiced a man overboard when the winds ripped the cushions off the foredeck, stopped all the work on the new bridge while the workers watched these crazy boaters retrieveing a cushion. But back to the original question, it does have the 330's and I think she's going to perform nicely. She's going back in the water next week then a 50 mile run back to her berth.

Uncle Bob,

As previously posted, we looked for a 1999/2000 3988 with 330's.

Found one in maryland and flew our broker out for sea-trial and survey.

330's on this boat had been abused, somekind of previous overheat lead to exhaust bypass and soot in the engine room, we passed.

Aside from that there were many other options we wanted and continued to look around, finally found one here in Seattle that had been priced higher than market would bear and sat around @ Blackfish for several months.

This boat has twin 270's which is what we purchased.

As we do not cruise past 16 to 18 knots, top speed is irrelevant. We have put upwards of 170 hours on these engines in the 2 summers we have had her.

Discussion with other BOC members and our Mechanic's (Breakwater tacoma & Cummins NW) any difference in performance is negligable.

As for economy, we typically use 1/2 Gallon of diesel per engine for each mile we travel. last logged trip was from gig harbor to Roche Harbor, through Deception, around August 5. GPS Tracked 118 Miles, average speed was 14.8 kts. with top speed reading @ 19 kts. (This is from GPS and is speed across ground).

We topped off before leaving for further north and took exactly 119 gallons, so 1 mpg with both engines running is pretty true to form.

Typically RPM @ around 2,500 is optimal, which is approx. 16 to 18 kts. (Depending on current, trim etc.)

I've never had a boat with 330's, so my only experience is with the 270's.

I love the Cummins Engines, alot of service providers in and around puget sound (Due mainly to the sheer number of Bayliners with Cummins Engines), they are true workhorses.

I have heard that there may be some economy issues with the 330's, but I dont know.

Ours is still for Sale, if you know anyone looking.
